Ytterbium-Doped Fiber

Ytterbium-Doped Fiber

Ytterbium-doped fiber includes two structural types: double-clad and triple-clad. It can output high-power laser in the 1 μm band and is mainly used in ytterbium-doped fiber lasers and amplifiers. With advantages such as high output beam quality and good stability, it is widely used in military, industrial, medical, and scientific research fields. By adjusting fiber parameters, ytterbium-doped fibers of different sizes and shapes can also be provided to meet various application requirements.
